Main changes

  • Extended the benchmark from 21 to 30 tasks by adding the following:
    • Activity selection (Gavril, 1972)
    • Longest common subsequence
    • Articulation points
    • Bridges
    • Kosaraju's strongly connected components algorithm (Aho et al., 1974)
    • Kruskal's minimum spanning tree algorithm (Kruskal, 1956)
    • Segment intersection
    • Graham scan convex hull algorithm (Graham, 1972)
    • Jarvis' march convex hull algorithm (Jarvis, 1973)
  • Added new baseline processors:
    • Deep Sets (Zaheer et al., NIPS 2017) and Pointer Graph Networks (Veličković et al., NeurIPS 2020) as particularisations of the existing Message-Passing Neural Network processor.
    • End-to-End Memory Networks (Sukhbaatar et al., NIPS 2015)
    • Graph Attention Networks v2 (Brody et al., ICLR 2022)

  • Fix samplers_test by @copybara-service in #47
  • Update requirements.txt by @copybara-service in #45
  • Bug in hint loss for CATEGORICAL type. The number of unmasked datapoints (jnp.sum(unmasked_data)) was computed over the whole time sequence instead of the pertinent time slice. by @copybara-service in #53
  • Use internal rng for batch selection. Makes batch sampling deterministic given seed. by @copybara-service in #49
  • baselines.py refactoring (6/N) by @copybara-service in #52
  • Time-chunked datasets. by @copybara-service in #48
  • Potential bug in edge diff decoding. by @copybara-service in #54
  • Losses for chunked data. by @copybara-service in #55
  • Changes to hint losses, mostly for decode_diffs=True. Before, only one of the terms of the MASK type loss was masked by gt_diff. Also, the loss was averaged over all time steps, including steps without diffs and therefore contributing 0 to the loss. Now we average only over the non-zero-diff steps. by @copybara-service in #57
  • Adapt baseline model to process multiple algorithms with a single processor. by @copybara-service in #59
  • Explicitly denote a hint learning mode, to delimit the tasks of interest to CLRS. by @copybara-service in #60
  • Give names to encoder and decoder params. This facilitates analysis, especially in multi-algorithm training. by @copybara-service in #63
  • Symmetrise the weights of sampled weighted undirected Erdos-Renyi graphs. by @copybara-service in #62
  • Fix dataset size for augmented validation + test sets. by @copybara-service in #65
  • Bug when hint mode is 'none': the multi-algorithm version needs something in the list diff decoders. by @copybara-service in #66
  • Change requirements to a fixed tensorflow datasets nightly build. by @copybara-service in #68
  • Patch KMP algorithm to incorporate the "reset" node. by @copybara-service in #69
  • Allow for multiple-batch evaluation in example run script. by @copybara-service in #70
  • Bug in SearchSampler: arrays should be sorted. by @copybara-service in #71
  • Record separate hint eval scores for analysis. by @copybara-service in #72
  • Symmetrised edges for PGN. by @copybara-service in #73
  • Option for noise in teacher forcing by @copybara-service in #74
  • Regularize PGN_MASK losses by predicting min_value-1 at missing edges instead of -10^5 by @copybara-service in #75
